hi everybody, we will soon upgrade our 16 slot CRS-1 to CRS-3, which means going from 40Gbps/slot to 140Gbps/slot. afterwards, we will install a couple of 14X10GBE PLIMs with FP140 in the back. this will grant us more 10GE ports in an almost full chassis.
anyways, this process comes with high adrenaline level and huge risk because we have to carry out the upgrade in several steps: 1. upgrade from IOS XR 3.8.4 to IOS XR 4.0.1-px with downtime 2. upgrade fabric from FC40/S to FC140/S without downtime 3. migrate 10GE ports from 8-10GBE/MSC40 cards to 14X10GBE/FP140 cards we are concerned about quite a few things: a. how will the mix of MSC40 and FP140 within the same chassis work out? b. one of the datasheets we found about the new PLIMs says: "The XFP power dissipation is different for each vendor and range. Cisco Transceiver Module Group has released new "-L" class XFPs, XFP10GLR-192SR-L (10km) and XFP10GER-192IR-L (40km), for low power and low EMI to coincide with CRS-3 PLIMs. They are 1.5W and 2.5W respectively and the only 10km and 40km XFP types supported on CRS-3 XGE PLIMs. Standard XFPs like XFP10GLR-192SR are not supported on the CRS-3 XGE PLIMs. There is a strict UDI compliance check when an XFP is inserted or the LC has booted with XFPs. Non-supported XFPs won’t be powered on." we only use 3rd party optics, of course. just curious if anybody has experience with these PLIMs and the optics that work with them. c. what about the new IOS XR 4.0.1-px? did anybody ran into any kind of problems regarding a P router with this version? d. anything else that might be helpful with the new hardware above? thanks in advance and best regards, manu _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
